Ответы и объяснения

Hot or cold, what could it be? 
Summer is here just look and see
It's not winter or autumn here
Summer is something we shouldn't fear
Summer is out and it's time to play
Have fun because summer is not here to stay
Jump in the pool and play all day
Let's come on out and head for the bay
Summer time is once a year
Come on out without any fear
Plant some flowers for a summer day
As long as summer is here to stay
